koko is indeed QI.
Sadly, you felt the need to both quote mine and not provide the source, which is not the kind of behaviour I expected of you - i came here to discuss and learn not point score at all costs. However, I'm an atheist and a rationalist so I am capable of true forgiveness.
Here's the full paragraph
During the course of the study, Koko has advanced further with language than any other non-human. Koko has a working vocabulary of over 1000 signs. Koko understands approximately 2,000 words of spoken English. Koko initiates the majority of conversations with her human companions and typically constructs statements averaging three to six words. Koko has a tested IQ of between 70 and 95 on a human scale, where 100 is considered "normal." Michael, the male silverback gorilla who grew up with Koko, had a working vocabulary of over 600 signs.
So Koko has been intensively trained since near birth and for 40 years by a very dedicated team of people and has learned around 2000 signs. She's been rewarded when she she gets it right and as a result has apparently achieved the language IQ level of a sub-normal human.
Unfortuantely, the team 'publish' most of their findings via the mass media - there are a few peer reviewed papers but I haven't seen any. I do know that there is a lot of controversy surrounding what she actually understands and what she's merely been conditioned respond to.
However, I did see a documentary on Koko a couple of years and I was very impressed; from watching it I'd say that she definately understood some things and is fairly obviously not clueless.
But really, she's not even on the same page as us. Not even close.
Life, don't talk to me about life.
